Factors that affect the electric field between 2 objects.
Charge, Distance
Occurs when 2 objects are rubbed together, causing a transfer of electrons between the objects.
friction
A material through which charges can move freely.
Conductor
An object that has a positive charge equal to its negative charge
neutral
Positively charged ions have
more protons than electrons
The force exerted by any 2 charged objects on each other.
electric force
A build up of electric charges on an object.
Static Electricity
a material through which charges cannot move easily.
Insulator
The electrons lost by one object are ___________ by another.
gained
Negatively charged ions have
fewer protons than electrons
has a negative charge
electron
A Generator that places a charge on its dome and uncharged objects that touch the dome becomes charged by contact.
Van de Graaff generator aka Plasma Globe
A special class of materials that conduct electric charge better than electrical insulators but not as well as electrical conductors.
Semiconductors
Like charges tend to...
repel
Dense center of an atom
nucleus
Has a positive charge
proton
The loss of charges
electric discharge
the purpose of the material surrounding the metal inside a lamp cord.
insulate( prevent shock)
Opposite charges tend to...
attract
2 parts of the nucleus
protons and neutrons
has no charge
neutron
The way of rearranging the charges within an object without touching it.
Induction
Iron , metal, copper wire
conductors
Atom has an overall positive or negative charge
ion
Found outside of the nucleus
electrons
